>> well, if you listen to the romney campaign and to governor romney himself, he seems to have a more marshal approach to international affairs. he seems to think that maybe by leading with military force, by being more bold on the international stage, america can be defended ber. but i think that governor romney has not been able to articulate a compelling vision of how he would actually strengthen america. he's been vague about when he would get us out of afghanistan. i think frankly he has not really spoken very clearly about how he really differs from president obama on iran. i suspect their two positions are fairly close actually. >> ifill: on the same point, richard haas? >> i actually think there is a difference on iran. the president is clearly saying that iran cannot be allowed to have a nuclear weapon. governor romney has been stricter that they can't be allowed any enriched material and clearly he wants to stop iran somewhere short of a nuke already weapon. i think again that's going to be part of the debate. what is it we can tolerate? can i make another point for a second
